3. Water has no taste,
no smell and is transparent. There
are three physical forms:
solid (ice), liquid and gaseous (vapor).
It is a good solvent,
it is the only substance
which expands when it freezes.
4. Water is involved in important processes in the body, such as breathing and
the conversion of food into energy, and therefore the adoption of less water
than necessary leads to dehydration.
5. What exactly is?
Water is one of the largest and necessary resources on Earth.
t is vital , both for humans and for all other Organisms, from the
smallest amoeba to the big scary whale, from the smallest seed to
majestic redwood . About 2/3 of Earth's surface is covered with wate
Water is essential for sustaining life on Earth. Man can survive
weeks without food and even months, but without water
n a single day is a real challenge. Life on Earth was born in the wat
billions years ago and in our days it continues to depend on it.

6. The amount of water in Bulgaria is
not much. Considering the water
resources per capita, our country
ranks among the last in Europe.
Water wealth is unevenly distributed
throughout the country.
8. • Surface water includes all rivers, lakes
and reservoirs throughout the country.
They are important for the water
balance of Bulgaria. The amount
depends mainly on rainfall. Surface
waters occupy over 90% of usable water
in the country.
9. • Groundwater in Bulgaria are important
for shaping the nature and are a great
human need. Groundwater is found both
in the mountains and in the plains and
hilly areas. According to their formation,
they are divided into: ground, karst,
pressure and mineral.
10. There are known three
systems of water
consumption:
• linear - single use water for now it is
a major (90%)
• consistent - allows wastewater from some
activities to be used by others without returning
to river receivers
• trial - closing the water consumption within
a system, this system is most effective
11. Water of Bulgaria are mainly
used for irrigation, domestic
and industrial needs. Scientists
predict that water
consumption will increase to
such an extent that satisfying
the needs will become very
difficult.
Use of water from major rivers will rise, but they are very
contaminated. Their main pollutants are wastewater
from industrial and domestic waste.
12. But water pollution is not associated with them. What happens to
the animals inhabiting these waters? It certainly is not a good
thing. Why, when we open the Red Book, we see so many
endangered, threatened or even extinct species. One of the
reasons, we could say the main one, is exactly the pollution of
these waters.
13. As we already mentioned the water
substance in Bulgaria is not very
much. And if we don't want our
country to look like desert, we should
save this treasure, no matter how little
it is. Still, we are not the last people on
earth, aren't we!
14. Recently, purifying the
waste water is one of the
main national priorities.
Highly
contaminated
water, requires
immediate
measures to
improve their
15. With the development of scientific and
technical progress, there is an increase in
new and advanced technologies .That
makes water purifying more effective, but
it’s very expensive and a country like ours
can not afford it, or at least not entirely.
16. Any factory, farm, village have to
build treatment plant effluent.
Mandatory water must pass through
wastewater treatment plants. There
must be strict security and control of
all dams and other water sources.
17. But water protection is not only to not throwing waste in
it. Is more than that. It is saving it. We shouldn’t only
want, we have to give and appreciate what we have and
what we want to have.
